Super Saiyan Blue, also known as Super Saiyan God Super Saiyan (超サイヤ人ゴッド超サイヤ人Sūpā Saiya-jin Goddo Sūpā Saiya-jin), is a form that combines the power of Super Saiyan God with the first Super Saiyan form.
This form can be accessed by absorbing the powers of a god and then simultaneously activating them while transforming into a Super Saiyan, or through vigorous ki control training with a deity with godly ki and then obtaining that Godly ki for oneself, as seen with Vegeta in the Super anime. The god ritual is in other words not required, but it is the easier path to take. This form surpasses its predecessor, Super Saiyan God.
